Spotify will not Log In - Facebook Loop

[rachaney]

I have a Facebook linked Spotify account. Spotify logged me out yesterday (I didn't tell it to) and now will NOT let me log in. The "Log In with Facebook" button clicks and takes me to a web browser, but nothing changes on the Spotify page. I thought it was Google Chrome, so I switched default browers to Firefox. Now, the page will completely load and say "you can close this page now" but the Spotify pages remain the same. It's in a perpetual loop.

I tried using my username and password. Spotify says I am "being blocked by a firewall." I changed all my firewall settings to allow all apps through. No change. Error Code: 101

I have uninstalled and re-downloaded Spotify three times. I have removed it from my Facebook and re-installed it twice. I have changed proxy settings, browser security settings, and anti-virusware settings. I have even changed my Facebook password. Nothing has changed. 

I've had this problem a few times over the last years, and it's getting tiresome. Not sure why Spotify logged me out to begin with, but this added frustration is ridiculous.

FIXED: I uninstalled McAfee and everything works fine now.
